Mazdaspeed 3 - BNR S4 Turbo Install

In this video, we install the BNR S4 V2 turbo into the MS3 and get our first initial impressions on the base map. This turbo has great value and is what the car should have come with from the factory. It spools slightly later than the stock K04, but once it does, right around 3800 rpm, it kicks in hard! It doesn't taper off at higher rpm like the stock turbo does and is much more efficient at holding boost. Also, the smoother spooling characteristics reduces the potential for excessive wheel spin. This turbo can exceed the limits of the stock fuel system and stock block, and is the best modification that the car has seen thus far. Thanks for tuning and enjoy!
